A miniaturised dual-band circularly polarised (circular polarization) equilateral triangular monopole radiator for mid sub-6 GHz 5G G/WLAN operations is presented in this manuscript. The developed design comprises a planar microstrip equilateral triangular patch (T-patch) simultaneously loaded with O-shaped slot (OSS) and multiple-asymmetric rectangular slots (R-slots) at the centre and different locations of the radiator to enhance conventional T-patch performances. A pair of I-shaped slots (ISS) protracted degraded ground structure (DGS) to perturb the current distribution on the DGS and inverted H-shaped strip (IHSS) to accomplish dual-excitation mode and widening the impedance bandwidth (IBW). The calculation method and the attractive tri-group of orthogonal rectangular slots (ORS) to generate multiple bands and CP constitute the principal novelty of this study. The proposed design is configured on a thin lossless Rogers4003C material of volume 30.67 × 34 × 1.524 mm3. The measured performances show that the proposed manufactured radiator exhibits IBW of 37.74% and 18.34%, peak gain of 2.137 and 5.10 dB at 4.246 and 5.9426 GHz, respectively, axial ratio (AR) of 1.859 dB and simulated 3-dB axial ratio bandwidth (ARBW) of 3.25% at the upper operating frequency band (OFB). This antenna is suitable for wireless 5G application mobile phone and WLAN communication systems.
